20140016547 | METHOD FOR CONNECTING WIRELESS CHANNEL AND APPARATUS FOR PERFORMING THE METHOD - The method performed in the terminal includes generating a random value for wireless channel access, receiving a competitive index indicating a channel competition state from an access point, and determining whether to attempt a wireless channel access based on a comparison result between the random value and the competitive index. | 01-16-2014 |
20150117424 | METHOD OF SCANNING ACCESS POINT - A method of scanning an access point is disclosed. The method of scanning the access point includes creating a probe request frame including information created based on an identifier of an access point to be searched, and transmitting the probe request frame. Thus, it is possible to decrease the time and power consumed by a terminal when searching an access point. | 04-30-2015 |
20150124793 | METHOD FOR SCANNING FOR ACCESS POINTS IN WIRELESS LAN SYSTEM - Disclosed is a method for scanning for an access point in a wireless LAN system. An active scanning method comprises the steps of: transmitting a probe request frame to an access point; and receiving, from the access point, a probe response frame corresponding to the probe request frame. The probe response frame may include time information of a beacon transmitted after the probe response frame. Thus, the efficiency of a wireless channel can be improved in a wireless LAN system. | 05-07-2015 |
20150146524 | AID REASSIGNMENT METHOD, AND APPARATUS FOR PERFORMING SAID AID REASSIGNMENT METHOD - Disclosed are an AID reassignment method capable of optimally operating a wireless LAN system, and an apparatus for performing the AID reassignment method. The method comprises the steps of: generating a reconnection request frame for an AID reassignment request; transmitting the generated reconnection request frame to the currently associated access point; and receiving a reconnection response frame including AID reassignment information from the access point. Thus, the AID of the currently associated terminal can be dynamically reassigned according to a change in the characteristics of the terminal, thus operating a wireless LAN system in an optimum manner. | 05-28-2015 |
20150146568 | METHOD OF ACTIVE SCANNING AND ASSOCIATING BASED ON CONFIGURATION INFORMATION - Provided is a method of active scanning and associating based on configuration information, which can enable quick search for an access point (AP) and quick connection with a desired AP. The method includes transmitting, to an AP, a probe request frame including revision information of a current configuration, and receiving, from the AP, a probe response frame including the current configuration's revision information and/or updated configuration if any change has been occurred in a configuration designated by the prior revision information. Accordingly, when there are a plurality of terminals and APs, radio channel use efficiency can be improved by reducing the number and the length of unnecessary probe request frames and probe response frames to search for the AP. | 05-28-2015 |
20150146597 | METHOD FOR COMMUNICATING ENCODED TRAFFIC INDICATION MAP INFORMATION - Provided is a method of communicating encoded traffic indication map (TIM) information that can reduce power consumption by reducing an unnecessary decoding process. A method of receiving, by a terminal, a TIM that is encoded in a hierarchical structure including a page, a block, and a sub-block includes receiving an encoded TIM from an access point (AP), extracting a page index from the encoded TIM, and extracting block bitmap information indicating whether blocks included in a page designated by the page index include a bitmap. Therefore, an unnecessary decoding process with respect to each delivery traffic indication map (DTIM) beacon can be reduced, thereby reducing power consumption of a low-power terminal. | 05-28-2015 |
20150163666 | METHOD FOR CHANGING AID IN WIRELESS LAN SYSTEM - Disclosed is a method for changing an AID in a wireless LAN system. The method for changing an AID of a terminal by an access point comprises: a step of receiving an AID reassignment frame from the access point; a step of extracting an AID reassignment counter value from the AID reassignment frame; and a step of changing the AID of the terminal to the new AID included in the AID reassignment frame after the beacon periods of the access point indicated by the AID reassignment counter value extracted from the AID reassignment frame reception time have elapsed. Thus, a conflict between AIDs can be prevented. | 06-11-2015 |
20150223154 | ACTIVE SEARCH METHOD IN WIRELESS LAN SYSTEM - An active search method in a wireless LAN system is disclosed. The active search method comprises the steps of: transmitting, through an arbitrary channel, a preceding probe request frame for confirming the existence of an access point; acquiring, from at least one access point, a probe ACK frame that is a response to the preceding probe request frame; setting a maximum waiting time on the basis of the number of probe ACK frames; and performing an active search for an access point in the arbitrary channel for the maximum waiting time. Therefore, the waiting time for receiving a probe response frame can be reduced. | 08-06-2015 |
